* - called from ip6_input() (IPv6)
* - pbuf: received struct pbuf passed to ip6_input()
* - input_netif: struct netif on which the packet has been received
* Return values:
* - 0: Hook has not consumed the packet, packet is processed as normal
* - != 0: Hook has consumed the packet.
* If the hook consumed the packet, 'pbuf' is in the responsibility of the hook
* (i.e. free it when done).
